Origin and history

The thermal baths of Royat-Chamalières, located in the Puy-de-Dôme in Auvergne-Rhône-Alpes, have their origin in thermal springs operated from the Roman era. The remains of the ancient thermal baths, still visible, testify to this ancient association. At the time of the Revolution, the land was sold, allowing the development of first settlements such as the bath of the Poor (baths dug in the rock) and the source Caesar (discovered in 1822). These rudimentary installations, which became unsanitary in the face of the influx of curists, motivated the construction of a large thermal establishment between 1852 and 1856, designed by architect Agis-Léon Ledru.

The establishment, inspired by the Basilica of Constantine, is distinguished by its neo-antical facade with ionic columns and its rich interior decoration (mosaic, stained glass, stencil paintings). It initially housed 48 bathrooms, specialized shower rooms, and a swimming pool. Enlarged in 1857 and then in the late 19th century, the site enriched with a park, a drink (circa 1900), a casino and a theatre (1884-1890). Partly enrolled in historical monuments in 1990, it illustrates the golden age of spas, mixing hygienism, sociability and eclectic architecture.

The current thermal baths adjoin the Gallo-Roman remains, highlighting a thousand years of continuity. Their central forebody, flanked by gable side wings, serves vaulted galleries and a double-flyed staircase, illuminated by a zenithal glass roof. Ferronry, polychrome tiles and stencil-painted vaults reflect the opulence of the seaside facilities of the time. Private property, the establishment remains a major testimony of auvergnat thermalism, between ancient heritage and technical modernity.

The Caesar source, discovered in 1822, and the medieval infrastructures (like the hexagonal basin) precede the great source discovered in 1843. These successive discoveries, coupled with the enthusiasm for cures, explain the development of the site. The architect Ledru, inspired by the auvergnat novel to temper the ancient influence, created a hybrid building, both monumental and functional. Subsequent additions (south building, landscape park) responded to the tourist boom of the late 19th century, making Royat-Chamalières a popular destination of the European aristocracy and bourgeoisie.

The partial inscription to the historic monuments in 1990 concerns facades, roofs, the entrance hall (with its windows and drum doors), and galleries of the first class cabins. This classification highlights the heritage value of a combination of technical innovations (pulverized napkins, suction rooms) and sumptuous decors. The site, always dedicated to thalassotherapy, perpetuates a healing tradition of two millennia old, while embodying the fascists of the Belle Époque spale.
